L-series super telephoto zoom lens with image stabiliser.

High resolution, superb contrast, neutral colour balance, and Canon's original built-in Optical Image Stabilisation for compensation against blur caused by camera movement. The fluorite and Super UD-glass elements largely eliminate secondary spectrum. The floating system also ensures high picture quality at all focal lengths. The Image stabiliser has two modes and it is compatible with Extenders 1.4x and 2x.
